To put it another way, while it’s easy to see how a neuron could ‘store’ a scalar variable using epigenetics, it’s much harder to imagine that it could store a vector of values.
Of course a vector is just a scalar in disguise. Take Gödel numbering and you can store anything, even if all you have is unary coding.
Given the complexity of the genetic code, why would we just consider this implausible from the outset?
Depends on your system of computation. If all you can do to your numbers is add, multiply, but you don't have a eg a floor function, you can't do Goedel numbering.
